## Design and development

The aircraft was designed to comply with the [Fédération Aéronautique Internationale](/source/F%C3%A9d%C3%A9ration_A%C3%A9ronautique_Internationale) microlight rules. It features a [strut-braced](/source/Strut-braced) [parasol wing](/source/Parasol_wing) a two-seats-in-[side-by-side configuration](/source/Side-by-side_configuration) open cockpit, fixed [conventional landing gear](/source/Conventional_landing_gear) and a single engine in [tractor configuration](/source/Tractor_configuration).[1][2][3]

The aircraft [fuselage](/source/Fuselage) is made from welded steel tubing, with the wing built from [aluminium](/source/Aluminium) tubing with wooden [ribs](/source/Rib_(aircraft)). The airframe is covered in [doped](/source/Aircraft_dope) [aircraft fabric](/source/Aircraft_fabric). Its 11.34 m (37.2 ft) span wing has an area of 15 m2 (160 sq ft) and is supported by [cabane struts](/source/Cabane_struts), V-struts and [jury struts](/source/Jury_struts).
